What are the common microservice frameworks in java

Introduction to common microservice frameworks:

Spring Boot: This may be the best Java microservice framework. It is suitable for controlling feedback. Transformation, aspect-oriented programming, etc.

Sample code:

import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;
@RestController
@EnableAutoConfiguration
public class Example {
    @RequestMapping("/")
    String home() {
        return "Hello World!";
    }
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Example.class, args);
    }
}

Jersey: This open source framework supports Java's JAX-RS API and is very easy to use.

Sample code:

package org.glassfish.jersey.examples.helloworld;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
@Path("helloworld")
public class HelloWorldResource {
    public static final String CLICHED_MESSAGE = "Hello World!";
    @GET
    @Produces("text/plain")
    public String getHello() {
        return CLICHED_MESSAGE;
    }
}

Play: The framework allows you to easily build, create and deploy web applications using Scala and Java. The Play framework is ideal for RESTful applications that need to handle remote calls in parallel. It is modular and supports async.

Sample code:

package controllers;
import play.mvc.*;
public class Application extends Controller {
    public static void index() {
        render();
    }
    public static void sayHello(String myName) {
        render(myName);
    }
}
